为经济合理使用化肥,促进水稻施肥作业机械化。近两年来农垦二团在化肥的使用上有了新的改进,不但重视氮磷配合,而且在播种前将部分氮肥与全部磷肥混合条施或全部氮磷肥一次施入。 1980年该团场在十一连233号条田进行了对比试验,共分三种处理:一是每亩35公斤尿素加三料磷肥10公斤,播前一次施入土内,全期共用化肥45公斤;二是每亩尿素17.5公斤加三料磷肥10公斤,播前施入土内,生长期追尿素25公斤,全期共用肥52.5公斤;三是播前只施三料磷肥10公斤,生长期追尿素42.5公斤,全期共用化肥52.5公斤。按10株调查结果:处理 Economical and rational use of fertilizers to promote mechanization of rice fertilization operations. In the past two years, the second group of Nongken has made new improvements in the use of chemical fertilizers, not only attaching importance to the combination of nitrogen and phosphorus, but also applying some nitrogenous fertilizers together with all the phosphate fertilizers or all the nitrogenous and phosphate fertilizers once before sowing. In 1980, the field test was carried out in the field of No. 11 Lianlian 233 and was divided into three treatments: one is 35 kg of urea plus 10 kg of three-pot phosphate fertilizer, the other was applied into the soil one time before sowing, and the fertilizer was used for the whole period 45 kg; the second is 17.5 kg of urea per kilogram plus three kilograms of phosphate fertilizer 10 kg, sowing into the soil prior to sowing, growing period of urea 25 kg, 52.5 kg of fertilizer during the entire period; In the growing period, it recovers 42.5 kilograms of urea and shares 52.5 kilograms of chemical fertilizers in the whole period. According to 10 survey results: treatment
